Industry impact

Widespread simultaneous tropical activity across two ocean basins raises the odds that flight planning and dispatch will face overlapping weather deviations rather than a single isolated storm.

What happened

Meteorologists at the National Hurricane Center were tracking nine storms and potential storms early Monday, August 24, 2026, seven in the Pacific Ocean and two in the Atlantic Ocean.

In Hawaii, Tropical Depression Moke passed approximately 300 miles south of the islands after being downgraded from a tropical storm. Wind gusts were forecast to reach up to 55 mph over the Big Island and 45 mph over Oahu and Kauai. Portions of the Big Island and eastern Maui were forecast to receive an additional 3 to 6 inches of rain through Monday, bringing total rainfall on parts of the Big Island to 15 inches. The hurricane center warned the rain could cause life-threatening flooding and mudslides.

Tropical Storm Iselle formed on August 23 well off the Mexican coast. As of 5 a.m. August 25, it had 60 mph winds and was located 540 miles southwest of the southern tip of the Baja California peninsula. Iselle is forecast to briefly reach hurricane strength while moving northwestward without threatening land, then weaken to a tropical depression within five days. Four additional potential storm areas were being monitored across the Eastern Pacific. In the Atlantic, an area of showers and thunderstorms about 400 miles southeast of Bermuda had a 50% chance of forming into a short-lived depression or storm over 48 hours as it moved northward, and a tropical wave expected to move off the coast of Africa was being monitored as it moved westward at 15 to 20 mph across the eastern and central tropical Atlantic. Meteorologists noted that strong winds associated with El Niño in the Pacific have made it difficult for major storms to form in the Atlantic this summer, while cautioning that hurricanes have formed during past El Niño summers.
